(a) 264 Gms of CO2 is liberated during complete oxidation of 180 gms of glucose. (b) a-ketoglutaric acid is first dicarboxylic acid formed during Kreb’s cycle. (c) Number of ATP molecules formed by complete oxidation of pyruvic acid is 15. (d) Mercury is used in anaerobic respiration experiments because it does not react with CO2. (e) Rate of respiration is measured by respirometer. (f) Fermentation was discovered by Gay Lussac. (g) Enzyme extracted from yeasts which brings about the fermentation is zymase. (h) Fruits and seeds are stored at low temperature to reduce the rate of respiration. (i) If a leaf is kept in sugar solution, the rate of respiration increases. (j) Dinitrophenol inhibits ATP synthesis (uncoupler of oxidative phosphorylation). (k) Oligomycin inhibits oxidative phosphorylation (energy transfer inhibitor). (l) Abnormal rise in respiratory rate of ripening fruits is called climactric e.g. banana
